A launch party for Jay-Z's new album was brought to an abrupt halt last night when New York authorities shut down the city's Avalon nightclub.

Jay-Z refuses to hit back at Cam’ron over his 'diss track', which brands the 99 Problems rapper 'ugly' and even brings the hip-hop mogul's long-term love Beyoncé Knowles into the mix.

Jay-Z’s jarring video for 99 Problems, which depicts his own murder as a metaphor for his retirement from rapping, leads the MTV Video Music Awards with six nominations.
